The Arista 7500R Data Center Switch Router Series are designed for large enterprise virtualized and cloud networks that deliver a high-performance universal spine switch. It combines 100GbE density with Internet scale table sizes with comprehensive Layer 2 and Layer 3 features. The Arista 7500R Series delivers high performance with 150 Tbps of system throughput to meet the needs of large scale data centers, enabling highly scalable cloud network designs with MLAG, ECMP and VXLAN technologies. The Arista 7500R can be deployed in a wide range of open networking solutions, including large scale Layer 2 and Layer 3 cloud designs, overlay networks, and virtualized or traditional enterprise data center networks. Deep packet buffers and large routing tables allow for Internet peering and enterprise grade security between data center interconnect applications and provides complete deployment flexibility.

What's new

Delivers 150 Tbps of system throughput to meet the needs of very large scale enterprise data centers.

Designed for near continuous operations and with system wide monitoring of hardware and software components, simplfying serviceability and provisioning.

A wide range of modular systems with a single consistent Extensible Operating System (EOS) allows for flexible selections at all tiers of the network and deployment scenarios including Layer 2 MLAG, Layer 3 ECMP, VXLAN Overlay and Internet peering.

High-Performance Cloud Networks

The Arista 7500R Data Center Switch Router Series delivers a suite of advanced traffic control and monitoring features to improve the agility of modern high-performance environments, with solutions for automation, data monitoring, precise timing and next-generation virtualization.

Automating the data center enables customers to dynamically provision computing resources in the most efficient manner while also meeting business needs by maintaining service level agreements (SLAs).

Arista Extensible Operating System (EOS)

All Arista products including the Arista 7500R Data Center Switch Router Series deploy the same Arista EOS software, binary image simplifying network administration with a single standard across all switches.

Arista EOS is a modular switch operating system with a unique state sharing architecture that cleanly separates switch state from protocol processing and application logic.

Built on top of a standard Linux® kernel, all EOS processes run in their own protected memory space and exchange state through an in-memory database.

This multi-process state sharing architecture provides the foundation for in-service software updates and self-healing resiliency together with stateful switchover without the loss of data plane forwarding.

Arista EOS automates complex IT workflows and simplifies network operations while reducing downtime. It’s rich automation capabilities not only reduce the human error element in network operations but also enables IT operators to make the network work the way they want.
